This patch changes the 4 select statements in C4::Calendar::_init. tests for this method were included in a previous patch. There are more potential problems in C4::Calendar::delete_holiday, but that method seems to have deeper bugs than just these. I'll open another bug for them if I can figure out how it's supposed to work. No documentation changes necessary. Signed-off-by: Joshua Ferraro <jmf@liblime.com>
